Non-Fermi liquids from holography
Non-Fermi liquids from holography
We report on a potentially new class of non-Fermi liquids in ($2+1$)-dimensions. They are identified via the response functions of composite fermionic operators in a class of strongly interacting quantum field theories at finite density, computed using the AdS/CFT correspondence. We find strong evidence of Fermi surfaces: gapless fermionic excitations …
